Good street brands? I want to remove the damper. and stock fpr to run new lines. The two i keep coming back to is the turbosmart 800 or the Tomei type L. Is it worth the extra 50 dollars (plus fittings) for the turbosmart? Or is the tomei plenty for up to 600horses? Need help deciding???? Also, if i can run it properly, i want to tee either side of the stock rail to supply more flow to injector 6. Has it been done. Is it worth the effort? Cheers Craig
1. Noob questions here but what happens to the damper ? 2. If it isnt required why was it put in there in the first place? 3. I understand what you are saying about the teeing off ( or at least what you are about to do )but does that mean the stock fuel setup "starves " injector 6 ? Timely thread as I am coming up to this exact point in my rebuild. Sorry for slight threadjack.
1. Bined (tossed, thrown to the sh*thouse if you will) 2. Nissan overkill 3. means the fuel is consumed by 1-5, there isnt enough to go around and no 6 misses out somewhat.
3. There has to be insufficient fuel and pressure to starve 6 - that is why there is an FPR to pressurise the entire system.
2. I dont think Raheens answer is helpful by saying its an overkill as this is purely argumentative and debateable. Fluids transmit shock so well that liquid injection is used now to shear rock walls off rock faces. Ask a fireman why he never runs the hose direct to the pumper from the hydrant but makes a loop instead. A fluid engineer will tell you that the damper is essential as it reduces liquid shock pressure that prolongs the life of all the components on your fuel line system from the pump to the regulator. Without it you could end up damaging or giving early failure to any of those components in between including the injector o-rings which could result in a leak obviously, in fact it could even induce cracking into the rail itself. Have you ever wondered why the fuel inlet / outlets always run around in a U or O shape rather than run direct to the components - again this is to reduce the shock and jump from fluid transfer shock. So is it still an overkill?? It is no different to considering heavy duty springs/ suspension. The ride can be much better but it can induce stress cracks into the chassis/ body from the increase in shock stress. Ask people and you will hear some that have had cracks and others that have had none. So like the damper this is not an overkill but rather argumentative and debateable. If you plan to race the engine and strip everytime then a racing engineer would say dont worry about it. If you plan to drive with reliability and low maintenance then a nissan engineer would say dont get rid of it. Your question doesnt refer to which side of the camp you are in, racing or reliabilty, so the answer cannot be given easily, but regardless of which camp you are in it will come ultimately down to your own decision and risks you are prepared to take for the gain/ if any. If you dlete the damper, then you can minimise the shock / jump by turning the pipes but this is minimal compared to a specific device that directly addresses this question. You can also put your largest flowing injuector into 6 and 5 with the least into 1 etc. As stated earlier you have to have not enough fuel or pressure to really affect cylinder 6 more than a minimal amount thats worth worrying about. Sure - if you are under pressure or fuel flow then yes 6 will be affected bigtime. I think your answer depends on other factors like how big are your injectors and whats your duty cycles etc etc. It doesnt give you the answer, that only you can provide yourself, but it does give you more food for thought and hopefully thats helpful.
